Orion Nebula(M42):

 

Right ascension: 

05: 35.4 (hours: minutes)

Declination:

 -05: 27 (degrees: minutes)

Distance:

 Approximately 1,344 light years

The Orion Nebula is a vast star-forming region located in 
the “sword” branching off of the famous Orion’s Belt. Also 
known as Messier 42, this diffuse nebula is bright enough to 
see with the unaided eye — although it will only appear as a 
slightly foggy star. However, with your telescope, you can see 
many of the beautiful details, such as the billowing clouds of 
gas and dust where new stars are being born.

Pleiades Star Cluster(M45):
Right ascension:

 03: 47.0 (hours: minutes)

Declination:

 +24: 07 (degrees: minutes)

Distance:

 Approximately 444 light years

The Pleiades Star Cluster is a group of brilliant blue 
stars located in the Taurus Constellation. Also known 
as Messier 45 or “Seven Sisters”, this open star cluster 
consists of more than 1,000 confirmed stars, although 
an average of only six are visible to the unaided eye. 
With your telescope, you can quickly reveal some 
of the more elusive members of this legendary and 
beautiful cluster.

Dumbbell Nebula(M27)
Right ascension: 

 19:59.6 (hours: minutes)

Declination:

 +22:43 (degrees: minutes)

Distance:

 Approximately 1,360 light years

The Dumbbell Nebula was the first planetary nebula 
ever discovered. It is one of the most popular sights 
in the Vulpecula constellation. Easy to find with 
binoculars and amazing in a telescope, the shape of 
this bright, double-lobed nebula has been compared 
to a dumbbell, an hourglass or an apple core. As an 
added bonus, the white dwarf that lies at the heart of 
the Dumbbell Nebula is larger than any other star of 
its kind.

Andromeda Galaxy(M31):
Right ascension:

 00: 42.7 (hours: minutes)

Declination:

 +41: 16 (degrees: minutes)

Distance: 

Approximately 2.54 million light years

The Andromeda Galaxy is the closest major galaxy 
to our own Milky Way. Also known as Messier 31, 
this famous spiral galaxy is part of the Local Group 
of galaxies. Although it is technically bright enough 
to see with the unaided eye under a very dark sky, 
your telescope may show its bright center, hints of 
its spiral structure and its much smaller companion 
galaxies known as M32 and M110.
